It might seem a simple enough concept at a glance, but actually allows quite a complex network of information. In practice, it's very intuitive and simple to use, and we've found the "link trail" extremely helpful to better understand what's happening in a project or why a particular change was made.

attachement: links

The link syntax for attachments is as follows:

attachment:the_file.txt creates a link to the attachment the_file.txt of the current object

attachment:wiki:MyPage:the_file.txt creates a link to the attachment the_file.txt of the MyPage wiki page

attachment:ticket:753:the_file.txt creates a link to the attachment the_file.txt of the ticket 753 attachment:wiki:MyPage:the_file.txt

source: links

The default behavior for a source:/some/path link is to open the directory browser
if the path points to a directory and otherwise open the log view.
It's also possible to link directly to a specific revision of a file like this: source:/some/file@123
or like this to link to the latest revision: source:/some/file@latest.
If the revision is specified, one can even link to a specific line number: source:/some/file@123#L10
